Hi everyone,
I just bought my first Toyota Camry a couple of weeks ago, and had a question a about it. From the day I got it, every morning, or anytime it's been sitting for a long period, if I don't let it warm up before putting it into reverse, it makes a loud knock or clank kind of noise, that comes from the transmission, is this normal?

If I let it run for about a minute, it usually doesn't do that, but I've never had a vehicle do that before. Does anyone know what this is, is it normal, or should I have it checked out? Thanks!
